Sold-out beauty products are a blessing and a curse. On one hand, you can't have 'em instantly, so you're forced to join a waiting list, nag the store with questions about shipping schedules, and remind yourself that patience is a virtue.

Chances are, you're already well acquainted with the cult classics that sell out season after season — but that's just the tip of the iceberg. For more, we asked five of our favorite NYC beauty destinations for the newest, coolest, and most under-the-radar discoveries that fly off their shelves and customers stockpile. A word of advice: When you find one of these, don't think — just buy.
